[Eric] Stack dump at breakpoint and other suggested improvements.

[Piotr Holonowicz]

Hi!
Eric4 is a really nice tool... but there are couple of things that could 
be improved:
- when eric displays a "bug" symbol at a faulty line of code, it is not 
currently possible just to left click on it to view the error message. 
Instead, a right click is needed then selection from context menu 
"Display error message". In my opinion it is slow to access and 
counterintuitive :(
- I would love to have a view of the python stack when the code stops at 
a breakpoint (although this I guess can be tricky to fix).
- most of the time the yellow line showing the current line of code does 
not appear, even when the code stops at a breakpoint, making debugging a 
nightmare (4.2.3 r2620 at kUbuntu Hardy).
- manual how to set up  the remote debugging hardly exists and it is not 
directly accessible from eric :(.

What do you think about the remarks above?

Best
Piotr
